11 years ago it just took one phone call to set up an appointment with Mayo ENT for my cancer. There is a lot of work arranging all your scans and medical information to be sent to Mayo. I believe a referral from your doctor can expedite the situation. Video visits are another option but you must submit all your information for these as well. I think a second opinion is always valuable to know you are heading in the right direction with your treatment. But you have received care at a highly rated cancer center and if you are comfortable with your doctors and their advice, just ask the question if the radiation and aftercare closer to home will be of the same quality as they can provide. Good luck to you.
